Toall'whomz'tmay consent? i Be it known thatI, Vrcron Lnn EMERSON,

' a citizen of the United States, residing at Alexandria, State of Virginia, have m-' vented certain new and useful Improvements in Universal Joints, of iwhich the following is a specification. 1

Among the objectsof invention is the construction of a universal joint which is light, compact in form, cheap to manufacture, oil-tight, dust proof, of few parts andeasy to assemble.

Body .member 3 has bores. 17 and 19 to receive the. head 16 and ball members 5. As will be seen, these bores are formedwith continuous walls which are die-pressed from a single piece Of metal.

The body piece 3 has a flange thereon which is'secured to-the flange15 by bolts 23 passing through registering holes 20. body piece 3is such-a; design as to be from sheet metal leaving the circular-form 7 T at one endconnectingthesbores" and the" flange 15 turned over at right angles the bores at the other end' so asto "form a bracing to resist the torque due to'the rotathe oflattaching the body'to the 1 flanged coupling.

In a universal joint, in combination, a body member provided with receptacles for the reception of a rotatable member, a flanged coupling provided with means for receiving a rotatable shaft and connected to said body member, said flanged coupling being recessed below the flanged surface thereof and having depressed portions of similar cross sectional contour to said receptacles and mating with the same to give greater longitudinal clearance to said rotatable member, and a retaining nut on said rotatable shaftand situated Within said recess.

In a universal joint, in combination, a body member provided with receptacles having axes parallel to the axis of said body member/co receive a rotatable member, said rotatable member having members contact ing with said receptacles and having a longitudinal movement therein, and a flanged coupling bolted to said body and having depressions therein in alinement with said receptacles and extending on the face of said flange beyond the radial'line of said bolts and between the same.

4. In a universal joint in combination, a body member having a groove on one end, a rotatable shaft carried by said body memher, a groove on said rotatable shaft, and a dust cover between said body member and said shaft, elastic means adapted to retain portions of said cover in said grooves, said cover having means to retain said elastic means in connection therewith, whereby said cover is held between said shaft and body.

5. As an article of manufacture, a pressed metal body for the purpose described, having receptacles Whose exterior contour is similar to the interior contour thereof and Whose axes are parallel to the axis of said body, and having a flange at the end of said receptacles extending at an angle to the axis thereof, forming an attaching member for said body.

(3. As an article of manufacture, a pressed metal body for the purpose described, having receptacles whose exterior contour is similar to the interior contour thereof and whose axes are parallel to the axis of said body, said receptacles forming a structure which has greater and lesser axial diameters, and having a flange formed at one end and means for attachment disposed therein on opposite sides of the greater diameter of said structure. l

7. As an article of manufacture, a pressed metal body for the purpose described, having intersecting circular receptacles with continuous walls whose exterior contour is similar to the interior contour thereof and whose axes are parallel to the axis of said body, said receptacles forming a structure which has greater and lesser axial diameters, and having aflange formed at one end and means for attachment disposed therein on opposite sides of the greater diameter of said structure, the other end of said body having an annular projection formed with an outwardly turned edge at the extremity thereof. p

In testimony whereof I affix my signature in presence-of two witnesses.
